"v eh icle Wheels,

of which the following is This "invention relates to road vehicle 'wheels ot the type in which a detachable rini carrying a pneumatic or other tyre is mounted between a .tixed and a detachable `ilange on the wheel periphery. The object ott the invention is to provide an improved wheel construction adapted particularly to what are known as fiat sided tyres.

.li-litherto the detachable rini has been iorined "with a pair of grooved edges 'for engagement by beaded edges on the inner periphery of the tyre, and this riin has been mounted between grooves in the fixed and detacl'iable wheel flanges. Also the riin has been made contractible to permit convenient application and withdrawal. olf the tyre. The said construction is, howevero not snitn "able tor fiat sided tyres as the latter have no beaded edges which can be engaged by the inade conti'actible or collapsible and in which the inner sides ot the .tlaiige are at right angles to the base of the rim, the outer sides ot the flanges being adapted to be engaged by `grooves in the tinedand detachable wheel flanges.

lle'lierrinn' to the accompanying sheet of explanatory drawings Figure Ll is a cross section of the periph` eral portion ot a wheel constructed in aecordance with this invention.

Fig. 2 is a sectional side elevation of a portion oit the wheel.

nel section providing `a pair of outward `flanges (t at the opposite edges ot the base or inainportion 7? of" the riin on which the tyre as o is placed. The inner sides ot these ilang'es are at right angles to the base, and the outer sides are rounded. in cross section `to engage correspondingly shaped grooves in the Inain fined and detachable flanges al7 c oit the. wheel. The outer circinnierential portions oif thelatter flanges are preferably Vsplayed outwardly as shown to avoid cutting` of the tyre. i

The detachable rini can be made conti'actible in any convenient manner. Thus it inay be divided transversely so that in the process oit contraction one end can be caused to overlap 'the other. Ur it may he fitted with a short removable segment, which when removed permits the ends ot the rim to be brought together. @r the riin may be con structed with one or incre relatively long segments enabling the rim to be collapsed.4

By this invention a well known wheel construction extensively employed 4lor beadededire tyres is very conveniently adapted for flat. sides tyres. l

AHaving thus fiiescribed iny invention what l claim as new and desire to secure by lietters Patent isz- .in a .road vehicle wheel ol" the type specitied the combination ot a detachable riin tor carrying1 a tire having Ltlaiiges at its edges,

" the inner sides oi' the flanges being arranged at right angles to the peripheral suritace oi" the rim and the outer sides being of convex torni, coasting .lined and denichable flanges on the wheel and each having an inner groove to grip the outer curved surface ot the flanges ot the rini and outwardly flared cirouin'ferential portions and means `for clamping the 'flanges on the wheel and about the riin,` substantially as described.

ln testimony whereof li have signed my name to this speciiication.
